Convert Grays per hour to Rads per hour
Convert Grays per hour (Gy/h) to Rads per hour (rad/h) instantly and accurately.
Conversion Formula
rad/h = Gy/h × 100
About Grays per hour
The gray per hour (Gy/h) equals 1/3600 Gy/s ≈ 2.78×10⁻⁴ Gy/s. Used in radiation processing and source strength reporting: ¹³⁷Cs irradiator calibrations are expressed in Gy/h at a reference distance; IAEA food irradiation standards cite Gy/h for conveyor output; radiobiological experiments for cancer cell survival curves use Gy/h. 1 Gy/h = 100 rad/h = 1000 mGy/h.
About Rads per hour
The rad per hour (rad/h) equals 0.01 Gy/h ≈ 2.78×10⁻⁶ Gy/s. Standard unit on US emergency dosimetry instruments and civil defense survey meters; Chernobyl sarcophagus contact dose rates were hundreds of rad/h; criticality accident dosimetry and NRC incident reports continue to evaluate dose rates in rad/h. 1 rad/h = 0.01 Gy/h = 10 mGy/h.
